    Definition
  • Provides basic guidance on the effects of electric currents on livestock for use in the establishment of electrical safety requirements. Indicates values for the electrical impedance of the body of livestock as a function of touch voltage, the degree of moisture of the hide or skin and the(...)
  • Summarizes the basic parameters for lightning and their variability insofar as they apply to human beings and livestock.
  • Provides touch voltage-duration combination thresholds based on analysis of information concerning body impedances and current thresholds of physiological effects, as given in IEC/TS 60479-1. Such threshold combinations relate to specific environmental and contact conditions that determine(...)
  • Provides a summary of test methods that are used to determine the ignitability of electrotechnical products or materials from which they are formed. I
  • Presents a summary of published test methods that are relevant to determine heat release for electrotechnical products. It represents the current state of the art of the test methods and, where available, includes special observations on their relevance and use.
  • Reviews the work of IEC SC 50D, and latterly IEC TC 89, in the development of higher quality, more reproducible small test flames. It examines the series of elements that together make up a small laboratory scale test for the examination of burning behaviour and shows how these parameters have(...)
  • IEC/TR 61000-4-32 provides information about extant system-level high-altitude EMP (HEMP) simulators and their applicability as test facilities and validation tools for immunity test requirements. This report provides the first detailed listing of HEMP simulators throughout the worldand is the(...)
  • IEC/TR 61000-4-35:2009(E) provides information about extant system-level High-Power Electromagnetic (HPEM) simulators and their applicability as test facilities and validation tools for immunity test requirements in accordance with the IEC 61000 series of standards. HPEM simulators with the(...)
  • This technical report covers general considerations and guidelines on mitigation methods aimed at ensuring electromagnetic compatibility (EMC) among electrical and electronic apparatus or systems used in industrial, commercial, and residential installations. This technical report is intended(...)
  • This technical report (type 3) covers guidelines for the earthing and cabling of electrical and electronic systems and installations aimed at ensuring electromagnetic compatibility among electrical and electronic apparatus or systems. More particularly, it is concerned with earthing practices(...)
  • This technical report provides elements for: - the design of an adequate protection for civil facilities against the electromagnetic pulse due to a high altitude nuclear explosion, denoted in what follows by HEMP; - the evaluation of already existing protections with respect to stresses(...)
  • This Technical Report covers guidelines for the mitigation of external electromagnetic influences impinging upon a facility, aimed at ensuring electromagnetic compatibility (EMC) among electrical and electronic apparatus or systems. These influences include lightning, RF transmitters,(...)
  • Provides recommendations for the selection and testing where necessary of conductor stringing equipment and accessory items used for the installation of overhead conductors and overhead earthwires.
  • Provides information related to the design, construction and testing of electro-sensitive protective equipment (ESPE) that employs vision-based protective devices (VBPDs) for the sensing function for the safeguarding of machinery.
  • Identifies those problem areas relating to the safe operation of RBMK reactors and makes recommendations to improve the safety of those reactors. Is a technical report of type 3 and was developed with the participation of IAEA experts.
  • This guide is applicable to on-line analyser systems. It provides the necessary guidance for the system supplier and user to specify or design a complete analyser system from sample point in the process to the final output for display or control purposes.
  • Is intended as a guide to assist in the development of a specification for analysers and their associated support systems for enquiry purposes and the subsequent assessment of the bids presented by the prospective vendors.
  • IEC/TR 61838:2009 provides a survey of some of the methods by which probabilistic risk assessment results can be used to establish "risk-based" classification criteria, so as to allow FSEs to be placed within the four categories established within IEC 61226.
  • Provides recommendations for the selection and testing, where necessary, of conductor stringing equipment and accessory items used for the installation of bare and insulated overhead distribution conductors.
  • Applies to the design of multimedia equipment such as information and communications equipment or audio-video equipment and systems.
